To round the float value to 2 decimal places, you have to use the Python round (). df.round (0).astype (int) rounds the Pandas float number closer to zero. Example 1: Number of type float is converted to a result of type int. To round a number in python, a solution is to use the function round : >>> round (3.1415) 3 … A number has a fractional part. One such example is shown below. The round() function add one to the integer value after conversion, if the digit after the decimal point is more than 5. 10-23, or 2.99e-23 in Python.. One can cast float objects to int objects by discarding the fraction part using the int() function. Step 1: Create a numpy array with float values. Definition and Usage.
